Objective: To observe the clinical efficacy of grain-sized moxibustion in treating chemotherapy-induced myelosuppression for non-small cell lung cancer (NSCLC) and its effect on quality of life (QOL). Methods: Eighty NSCLC patients admitted to the Inpatient Department of Zhejiang Cancer Hospital between September 2016 and March 2018 were recruited and divided into an observation group and a control group by random number method, with 40 cases in each group. The two groups both received chemotherapy with paclitaxel plus cisplatin (TP regimen). The control group received oral administration of leucogen tablets starting from the first day of chemotherapy, 20 mg each time, three times a day, for consecutive 14 d; the observation group was additionally given grain-sized moxibustion, once a day, five days per week at a two-day interval, until the fourteenth day. The myelosuppression severity was observed and compared between the two groups prior to chemotherapy, at the 3rd, 7th and 14th days of chemotherapy; the QOL in the two groups was evaluated before chemotherapy, at the 14th and 21st days of chemotherapy. Results: Regarding myelosuppression, the peripheral blood indicators increased significantly at the 3rd day of chemotherapy in both groups (P<0.05 or P<0.01); at the 7th and 14th days of chemotherapy, the peripheral blood indicators presented a decreasing tendency in the two groups, but the level in the observation group was still significantly higher than that before chemotherapy (P<0.01); at the 3rd, 7th and 14th days of chemotherapy, the peripheral blood indicators in the observation group were higher than those in the control group (P<0.05 or P<0.01); the occurrence rate of myelosuppression in the observation group was significantly lower than that in the control group (P<0.01). The QOL score in the observation group was markedly higher than that in the control group at the 14th and 21st days of chemotherapy (both P<0.05). Conclusion: Grain-sized moxibustion can effectively improve myelosuppression after chemotherapy for NSCLC, reducing its occurrence and enhancing the patient's QOL.

Objective To investigate transcriptional expression and promoter CpG methylation status of A-kinase anchoring protein 12 (AKAP12) gene and analyze their correlation with clinical pathological stage in bladder transitional cell carcinoma. Methods AKAP12 mRNA expression level and promoter CpG metbylation status was measured by fluorescent quantitative RT-PCR (FQ-RT-PCR) and methylation specific PCR (MSP) in 30 bladder transitional cell carcinoma and adjacent normal tissues. The products of PCR were cloned and bisulfite sequenced. Results Decreased AKAP12 mRNA expression was demonstrated in 22 carcinomas (73. 3% ) and was significantly associated with turnout grade (P =0. 02).The frequency of promoter methylation of AKAP12 gene was 53. 3 % (16/30) and correlated with the tumor stage(r =0.52,Pn =0.03)and grade(r =0.61,Pn =0.01). Conclusion Aberrant promoter methylation of AKAP12 can result in the loss of gene expression and may association with bladder transitional cell carcinoma.

OBJECTIVETo explore the therapeutic effects of posterior osteotomy and long-segment internal fixation in the treatment of senile thoracolumbar kyphotic deformity and provide the reference for operative treatment.

METHODSFrom April 2007 to April 2010, 19 older patients with thoracolumbar kyphotic deformity were respectively analyzed. There were 12 males and 7 females with an average age of 62 years (ranged, 58 to 74 years). Among patients, 11 cases were old fracture, 3 cases were ankylosing spondylitis, and 5 cases were old spinal tuberculosis. According to preoperative Frankel classification, 12 cases were grade E, 4 cases were grade D, 2 cases were C and 1 case was grade B. All patients were treated by posterior osteotomy and long-segment internal fixation and followed up above 1 year. VAS score preoperative, 2 weeks and 1 year after operation, Cobb's angle,n erve function and complication were observed.

RESULTSVAS score preoperative, 2 weeks and 1 year after operation separately was (7.0 +/- 1.2),(1.1 +/= .7) and (1.3 +/- .8); while Cobb's angle separately was (44.1 +/- .9), (10.9 +/- .1) and (11.5 +/- .8); there was significant difference in VAS score and Cobb's angle between preoperative and 2 weeks after operation (P < 0.05) w hile no significant difference between 2 weeks and 1 year after operation (P > 0.05). Eighteen cases met the standard of osseous fusion, 1 case occurred nonunion, but not looseness 1 year after operation. Nerve function: 3 cases changed grade E from 4 cases with grade D, 2 cases with grade C changed to grade D, 1 case with grade B changed to grade

BACKGROUNDThere are few studies to assess whether the effect-site concentration of propofol can predict anesthetic depth during the target-controlled infusion (TCI) induction in elderly patients. This study aimed to evaluate the relationship between effect-site concentration of propofol and depth of anesthesia during the TCI induction in elderly patients.

METHODSNinety patients (60 - 80 years) with an American Society of Anesthesiologists (ASA) physical status of 1 - 3, undergoing scheduled abdominal and thoracic surgery under general anesthesia were randomly allocated into one of three groups, Group S1, S2 and S3 (30 patients in each group). The patients in Group S1 received propofol with a target plasma concentration of 4.0 microg/ml; patients in Group S2 received propofol with an initial target plasma concentrations of 2.0 microg/ml that was raised to 4.0 microg/ml 3 minutes later; patients in Group S3 received an infused scheme of 3 steps; starting from a target plasma concentration of 2.0 microg/ml that was increased stepwised by 1 microg/ml until a target plasma concentration of 4.0 microg/ml was achieved, the interval between the two steps was 3 minutes. When an Observer's Assessment of Alertness/Sedation (OAA/S) score of 1 was achieved, remifentanil (effect-site concentration (Ce) of 4.0 ng/ml) and rocuronium 0.9 mg/kg were administered. Tracheal intubation was started 2 minutes after rocuronium injection. Changes of propofol Ce, blood pressure (BP), heart rate (HR), and bispectral index (BIS) were recorded.

RESULTSWhen an OAA/S score of 1 was achieved, Ce of propofol were (1.7 +/- 0.4) microg/ml, (1.9 +/- 0.3) microg/ml, (1.9 +/- 0.4) microg/ml and the BIS values were 64 +/- 5, 65 +/- 8, and 62 +/- 8 in Groups S1, S2 and S3. Before intubation, Ce of propofol was (2.8 +/- 0.2) microg/ml, (2.8 +/- 0.3) microg/ml, (2.7 +/- 0.3) microg/ml, and the BIS values were 48 +/- 7, 51 +/- 7, and 47 +/- 5 in Groups S1, S2 and S3. By linear regression analysis, a significant correlation between Ce of propofol and BIS values was found (r = -0.580, P < 0.01). Systolic blood pressure (SBP) before intubation was significantly lower in Group S1 than in Groups S2 and S3. SBP and HR after intubation in the three groups were significantly increased when compared with pre-intubation values, but they did not exceed baseline values.

CONCLUSIONSDuring the TCI induction, Ce of propofol with (1.9 +/- 0.3) microg/ml may make the elderly patients unconscious. When remifentanil with a Ce of 4.0 ng/ml is added a Ce of propofol with (2.8 +/- 0.3) microg/ml is suitable for intubation. The Ce of propofol has a close correlation with the BIS values. Also, a two-step TCI technique seems to be a more suitable method of anesthesia induction in elderly patients compared with the no-stepwise TCI technique and three-step TCI technique.

This study was aimed to construct the shRNA eukaryotic expression vectors of M2-pyruvate kinase gene (pkm2) and to investigate the effects of pkm2 gene interference on the drug resistance of acute promyelocytic leukemia (APL) cells in vitro. Three specific shRNAs of pkm2 gene were designed and cloned into PBSU6 vector containing a U6 promotor. The constructed plasmids were identified and proved by the restriction sequence analysis. Then the effect of pkm2-shRNA on the protein expression of endogenous PKM2 was detected in NB4R2 cells, a drug resistant cell line of APL by Western blot. The alteration of NB4R2 cell differentiation with the interference of pkm2 gene was also validated by nitroblue tetrazolium (NBT) reduction test. The results showed that three specific shRNA eukaryotic expression vectors targeting pkm2 were successfully constructed. The efficiency of pkm2 gene silence was proved at protein level. The interference of pkm2 gene could significantly enhance the cell differentiation in the drug resistant NB4R2 cell line. It is concluded that the DNA vector containing pkm2 targeting shRNA remarkably promotes the differentiation of NB4R2 cells, showing the prospects of developing the gene target drug.

OBJECTIVETo induce hepatic differentiation of human adipose-derived stem cells (hADSCs) in vitro.

METHODShADSCs were isolated from human adipose tissue and treated with improved hepatic medium containing HGF, bFGF and FGF4. After 7 days of culture, OSM was added to the culture media. Cell growth during hepatic differentiation was evaluated by CCK8 assay. Morphology of differentiation was examined under light microscope. Liver specific genes and proteins were detected by RT-PCR analysis and immunohistochemical staining, respectively. And functional characteristics of hepatocytes were also examined.

RESULTSThe number of hADSCs cultured in the improved hepatic media was increased significantly in comparison to hADSCs cultured in control media from 5 days to 21 days (t=6.59, 8.69, 15.94 and 24.64, respectively, P<0.05). The hADSCs-derived hepatocyte-like cells exhibited hepatocyte morphology, expressed hepatocyte markers, possessed hepatocyte-specific activities, such as uptake and excretion of indocyanine green, glycogen storage and albumin production.

CONCLUSIONhADSCs can be induced into hepatocyte-like cells in this differentiation system. And this differentiation system promoted the growth of hADSCs.

OBJECTIVETo observe the X-ray features of bone damage in patients with moderate endemic skeletal fluorosis and the changes of X-ray after treatment with herbal therapy.

METHODSFrom 2007.12 to 2009.8,114 patients with moderate endemic skeletal fluorosis were randomly divided into treatment group and control group by central randomization system. There were 60 patients in treatment group including 26 males and 34 females,aged from 39 to 60 years with an average of (51.68 +/- 4.98) years; There were 54 patients in control group included 30 males and 24 females, aged from 39 to 60 years with an average of (52.15 +/- 4.86) years. Both treatment and control groups were treated with basic treatment including calcium supplementation and preparation stage with herb decoction. Patients were orally given 600 mg Caltrate everyday for calcium suptrointestinal function and promoting the digestion and absorption of herb decoction for 3 days. Patients in treatment group were rally given Guo's Maqian decoction(200 ml,twice daily) for 8 weeks. Eight weeks later,Guo 's Maqian decoction was replaced y Guokangning capsule (0.44 g per cansule,2 capsules,three times daily) for 4 weeks. The treatment course lasted 12 weeks. The time for followed-up after treatment was 24 weeks. When the treatment finished, 7 experts on orthopaedics and radiology evaluated and statistically analyzed the X-ray features pre and post treatment,using expert evaluation scale (including the appearance and changes of osteosclerosis,osteoporosis softening,joint changes close to the bone and mixed changes) designed referring endemic skeletal fluorosis X-ray findings and sub-degree standard(WS192-2008).

RESULTSAll X-ray features of endemic skeletal fluorosis appeared in the X-ray of the 114 patients with moderate endemic skeletal fluorosis. Osteosclerosis: 4 cases in forearm, 7 in calf,4 in pelvis,4 in lumbar vertebrae ;Osteoporosis and bone softening: 23 cases in forearm patients, 23 in calf, 5 in pelvis, 8 in lumbar vertebrae; Mixed changes: 6 cases in forearm, 9 in calf, 10 in pelvis, 1 in lumbar vertebrae patients; oint changes: 107 cases in forearm, 47 in calf, 28 in pelvis, 19 in lumbar vertebrae. There were X-ray no changes before and after the treatment in all of parts in control group. In treatment group, there were only 2 patients showed extraperiostealin and joint changes after the treatment, in which one showed better ossification of interosseous membrane of leg and another one showed disappearance of the lateral hyperplasia of the left pelvic acetabulum. There were no changes between before and after treatment in X-ray of all parts in the rest patiens of the treatment group. There was no significant difference between before and after treatment in both groups (P > 0.05).

CONCLUSIONThere is no obvious improvement in radiology of patients with skeletal fluorosis treated by Guo's therapy.
